There usually are motives or reasons, so why don't you guys simply add the video and audio extensions. Are you guys associated with youtube a reason why you don't want to allow video uploads.
This was a huge turn down and I don't use you guys anymore. Besides this huge issue Your image and embedded video previews are way to little inside a template that's too little. You should allow users avatar to appear near the forum topics users create but I don't really mind this if the video upload is allowed.
Its your choice but It my choice not use you guys. It doesn't come close to facebook but if you did allow video uploads it would almost come close but right now since you don't allow video uploads it seems to the public your staff aren't capable of creating one or simply can't because they must be amatuers. Don't get upset at me but thats the impressions you guys give.
I showed people this software and there response was that they weren't that impressed with oxwall and that if there was no video upload what would be the reason of joining and oxwall website esp. if they have more options with facebook and that they would likely join if it had a video upload.
